Functionality

The protection relay is provided with a load profile recorder. The load profile feature
stores the historical load data captured at a periodical time interval (demand interval).
Up to 12 load quantities can be selected for recording and storing in a nonvolatile
memory. The value range for the recorded load quantities is about eight times the
nominal value, and values larger than that saturate. The recording time depends on a
settable demand interval parameter and the amount of quantities selected. The record
output is in the COMTRADE format.

Quantities

Selectable quantities are product-dependent.
If the data source for the selected quantity is removed, for example,
with Application Configuration in PCM600, the load profile recorder
stops recording it and the previously collected data are cleared.
